LID SUPPORT.

Application filed November The present invention relates to improve ments in lid supports and refers more parfully closedposition ofth e lid.

Another object of the invention resides" in 1 providing a lid support which will couir her-balancethelidand assist in the opening and closing moveinent thereof, aiding the operator in this respect.

T he device will be found pai'ticularly applicable for use' in connect-ion with phone graph and radiocahinetsi cedar and like chests, while it 'WlllELl'SO' be useful in connection withdooftrahsoins, swinging cellar doors swinging shelves, and otherobjec't's swinging about a horizontal" axis.

Vlthtll'B foregolng and other obgects in view; the" invention will be described more particularly infconnection with the accompanylng drawings and will'be more'particularly pointed out in the attached claims.

The other end of thelever or the end remote from the fulcrum pointis enlarged and forked or bifurcated as indicated in Figure 4 to produce the spaced fian esfi and 18 having lateral eiltensi'o nsll andQO projecting beyondthe plane "of the lever 9 and upwardly beyond'the upper longitudinal edge thereof. Betweenthe flanges 17 and 18 is a curved bearing nose'ei' adapted to come into contact withthe lower longitudinal edgeof the arm 10 whichis pivot ed'as indicated at 22"to the side wall of thecasing or other appropriatepart. The curved nose 21 frictional'ly engages said lower longitudinal edge of the arm 10' andresists the relative movement ofthese," two parts Moreover, the side flanges 1:7 and 18 frictionallyengage the opposite side surfaces" of the pivoted arm 10 and they furtherbindf upon the arm and increasethe' total friction resultant. I v v v The pivot point 23" \vl1icl1 attaches the pivoted arm 10 to the lower end of the link 11 is set inwardly from the free end ofj the arm '10 leaving a projefcting poijtion 24 of" the arm for the engagement of the laterally extending parts 1 9 and'QO of the lever 9, whereby to act'as' a guide formaintaining the pivoted arm 10 at all timeshetween the flanges, 'lhe lowerferid of 'tl elink 11 is so arranged and disposed that asubstantiail portion' of thedower edge of thel piivoteid n -Ope peter ret re wit the projectin -flan ep to pass beneat-lr thelinlg-lllp-withi r I disengagement of thefleve *andpivotefdfai In the operation-pf the "cle'vice; the spring 15 isdrawn-outerput un der te 'isihn iii-the closed-position f he l'd'fi as shown in Figare 1, The"p ratiojfl 'ii the" cable' -arid 15. lowever, upon ranthe lid through a small or .r d ice the activity of the spring 1!) will be ted in the other parts of the device. AS the lid is raised, the lever 9 will follow beneath the pivoted arm 10. being urged by the spring 15 so to do, and the saring will assist this raising movement of the lid. The flanges l? and 18 will gradually move up about the arm 10 and progressively increase the friction area on the sides of said arm L). This triction will oppose the action of the coil spring 15 and these two forces acting on opposite ends of the lever 9 will tend to balance the lever and to conseouently make oral very light touch necessary in moving the lid 6. lVhcn the lid is in a "ully opened position the projecting end of the pivoted arm 10 will strike beneath the bott 1111 or plate 8 of the cabinet and act as a stop. This stop arrangement might, however, be left out or provided by some other agency as particular requirements dictate.

In lowering the lid 6, the weight of the lid will of course, assist in this movement and this weight will be counter-balanced by the necessity for distending the spring fl?) and moving the parts of the lever 9 and arm 10 frictionally upon one another. As a con sequence, the lid may be maintained in any angular position and it can be shifted upon the lightest touch.

It is obvious that aarious changes and n'iodifica-tions may be made in the details o't construction and design of the above specifically described embodiment of this invention without departing from the spir't thereof, such changes and modifications berestricted only by the scope or the tollowing claims ll hat is claimed is zl. A lid support for cabin" and e comprising a lid stav secured the cabi et and to th lid, and lid-counterbalance me us independent of said lid stay and acting frictionally and resiliently on said stay to assist in raising the lid and for hol the lid in adjusted position.

2. A lid support for cabinets and the l comprising a lid stay coupled to the lid to the cabinet, and sliding-pressed lever sliding directly and frictionally againc stay for facilitating the opening and c o. movement of the lid and for l'ti'lllllnf lid in adjusted position.

3; A lid support for cabinets and the like, comprising a lid stay-coupled'to the cabinet and to the lid, a lever in said cabinet having an end frictionally sliding in contact with the edge of said stay, and means acting on said lever to cause the same to frictionally follow the movement of the stay in the act of raising and lowering the lid.

4. A lid support for cabinets and the like,

comprising a lid stay coupled between said and cabinet an the lid, a lever in said cabinet having a bifurcated end adapted to frictionally embrace said lid stay, and means acting on said lever for urging the same to follow the stay in its movement consequent upon the opening and closing of the lid.

5. A lid support for cabinets and the like, comprising a lid stay coupled to said lid and to the cabinet, a lever fulcrumed in the cabinet and having a forked end forming spaced flanges for frictionally grasping the lid stay, said flanges having lateral extensions.

6. A lid support for cabinets and the like, comprising a lid stay coupled to said cabinet and to the lid, and a lever fulcrumed in said cabinet and having rounded nose for engaging an edge of said lid stay and with flanges for frictionally engaging adjacent edges of said stay, and means acting on said lever for urging the same constantly against said stay.
